Circumstances:
On a crop spraying flight for the kolkhoz (collective farm) "Oktyabr" at Besedino (Kursk district of the Kursk region) when lifted off at low speed after a take off run of 300 metres (the crew had neglected the influence of the tail/cross wind). The aircraft stalled at a height of some 10-15 metres and crashed 235 metres behind the runway threshold, about 15 km east of Kursk. A pilot was killed while the second occupant was seriously injured.
Probable cause:
Premature liftoff on part of the pilot-in-command.

Aircraft flight hours:

Circumstances:
The single engine airplane was completing a cargo flight from Karam to Kazashinskoye, carrying two passengers, two pilots and a load of 1,194 kilos of potatoes. While in normal cruise, the crew informed ATC he was diverting to Yukhta for unknown reasons. Few minutes later, while flying in snow falls, the airplane struck trees and crashed in flames on the slope of a mountain located about 63 km north of Kazashinskoye. As the radio contact was lost and the airplane failed to arrive at destination, SAR operations were initiated but eventually suspended after few days as no trace of the aircraft nor the four occupants was found. The crew of an helicopter localized the wreckage on 21 June 1976. It was determined that the airplane struck trees at an altitude of 800 metres, got a little altitude then crashed 60 metres further in a forest. At the time of the accident, the visibility was probably below 2 km and below minimums.
Probable cause:
The decision of the crew to continue the flight in below weather minimums (snow falls) and not returning to his departure point. The accident was the consequence of a controlled flight into terrain.

Circumstances:
On a night approach to Saratov-Tsentralny Airport, the pilot allowed the aircraft to drop below the glide path. The twin engine aircraft hit the runway surface with a positive acceleration of 2.35 g, bounced and nosed down prior to hit the runway a second time with a positive acceleration of 3 g. The aircraft went out of control, veered off runway to the left and came to rest in flames in a grassy area. While the aircraft was destroyed, all 57 occupants were evacuated safely.
Probable cause:
Wrong approach configuration on part the of the crew who failed to follow the approved and published procedures.

Circumstances:
While cruising by night at an altitude of 7,800 metres, the electrical system failed, causing several instruments to fail, among them gyros. Control was lost and the airplane entered a dive and eventually crashed in a nose-down angle of 70° in an open field located 150 metres from the village of Verkhnyaya Khava, about 50 km northeast of Voronezh. Some debris of the airplane were found at a depth of 14 meters. It disintegrated on impact and all 111 occupants were killed.
Probable cause:
The 36 volts electrical system failed in flight, causing the automatic pilot system to fail as well as instruments such as gyros. Investigations were unable to determine the exact cause of the electrical system's failure. While flying by night and in a visibility reduced by clouds, the crew was unable to have visual references and lost control of the airplane after suffering a spatial disorientation.

Circumstances:
At liftoff, the right wing dropped and the airplane rolled to the right to an angle of 70°, causing the right wing to struck the snow covered ground 129 metres to the right of the runway. Out of control, the airplane crossed a taxiway, passed behind an air Koryo TU-154 that just landed (some debris struck the TU-154) and came to rest in flames, broken in three, 232 metres further. The wreckage was found 180 metres southeast of the runway end. 78 people, among them a stewardess, were injured, 12 people were unhurt. 24 occupants were killed, 15 passengers and nine crew members.
Probable cause:
The loss of control after rotation was caused by the combination of an asymmetrical fueling and pilot errors. It was determined that there was a difference of 1,500 kg of fuel between both wing tanks; 1,500 kg more in the right wing tank than the left wing tank, causing an excessive weight in the right wing. An excessive angle of attack after rotation above the allowable values and the lack of reaction from the pilot-in-command who failed to correct the situation for a period of eight seconds, caused the aircraft to reach an excessive right roll angle of 70° and to crash.
